Summary
-
1.
Convenient methods for the synthesis of 2-methyl- and 1,2-dimethyl-4-piperidones are proposed.
-
2.
Several variants of the synthesis of 1-(1,1-dimethyl-2-propynyl)-2-methyl-4-piperidone were examined.
-
3.
1-p-Tolylsulfonyl derivatives of 4-piperidones do not undergo the amino-exchange reaction when heated with primary amines in presence of caustic alkalies.
